Hello everyone I am looking and wondering what oil I should run in this vette? I read older threads but alas they are dated and now we have new oil formulations so that means different specs. I do like PUP 5w30 or M1 EP 5w30 but I am afraid the PUP may shear to a 5w20 in this engine. I don't plan on tracking the car so I wont be going to the ×w40 route unless I should or if it burns oil like crazy. Please let me know what you recommend thank you very much!!!
